Selector itself will remain printable AFAIK (however, the way it prints will become somewhat misleading to Swift code, as the Swift mapping of APIs diverges from ObjC). We'll likely want to phase out its StringLiteralConvertible-ness, though.</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>-Joe</div></font></span><div><div class="h5"><br><blockquote type="cite"><div><div style="word-wrap:break-word"><div><div><br><div><blockquote type="cite"><div>On 19 Jan 2016, at 23:43, Joe Groff via swift-evolution <<a href="mailto:swift-evolution@swift.org" target="_blank">swift-evolution@swift.org</a>> wrote:</div><br><div><div style="word-wrap:break-word">We discussed this proposal during our core team review meeting, and concerns were raised about the implementability of the proposed 'Selector(Type.method)' syntax.
